Agatized Botryoidal Chalcedony – Layered Growth with Smooth Overgrowth – Maharashtra, India

A distinctive specimen of botryoidal chalcedony exhibiting layered silica growth and partial agatization. Rounded chalcedony domes are overlain by a smooth, translucent secondary chalcedony layer, creating a soft, frosted visual effect while preserving the underlying botryoidal structure.

The contrast between darker, more lustrous chalcedony and the lighter overgrowth reflects stages of silica deposition within a volcanic cavity. The result is a piece with both depth and complexity, offering a unique variation on classic botryoidal chalcedony.

Bottom surface is cut and ground using the traditional techniques of the basalt miners in the Deccan Trap region.

Key Features:

·         Botryoidal chalcedony with partial agatization

·         Smooth secondary chalcedony overgrowth (not etched)

·         Layered silica deposition with visible growth phases

·         Combination of glossy domes and softly diffused surfaces

·         Subtle translucence and internal depth
